I have been using Advair 500 for 11 days. It was prescribed for asthma, which I have never had before. I was diagnosed with walking pneumonia in April and then concurrent with the pneumonia - asthma. I have been to two asthma/allergy specialists recently. One wanted to keep treating me with antibiotics and I said no. The second specialist prescribed the Advair. I immediately felt better...wheezing was gone inside of a week - completely. I am supposed to use the 500 for a month and then go to the 250. While I haven't gained any weight, I am unable to sleep, feel warm all the time, and am experiencing migraine type headaches, and neck pain. I've read some of the posts here and I am concerned that I've read about people stopping the Advair. Shouldn't one be weaned off the Advair like other steroids such as prednisone??? This is all very new to me and I just haven't felt well in over 2 months...want to get over it and get on with life. Thank you!!!
